These are generic designs ...manufactured by quite a few different places.I know that the Pentair tanks were not from this specific supplier but from KL aquatic but however were the same basic design. I believe Pentair has sourced these tanks from several different suppliers and some have had major issues with the paint bubbling off. This particular company is known for supplying all the high end Arowana farms and Ray breeders and have a good reputation. I’ve not seen any bubbling or peeling on the interior of any of the ones I’ve seen in the flesh.
One of the dealers in Singapore for this company (where there are literally hundreds of these tanks ...you see them everywhere) has a quite interesting webpage highlighting some of their installations
